Choosing the right control cable assembly is a crucial part of the designing and engineering of mechanical components and analog systems. Push pull control cables activate equipment by transmitting physical force through machinery. Though push pull cable operation may seem easy and effortless, there is a great deal of engineering know how and experience that is required to design the proper push pull control cable and pull cables to fit an application exactly.
The first consideration, regarding control cables and push pull cables, is the type of treatment they must endure and withstand in the harshest of conditions. To ensure the best and most reliable performance, Tyler Madison manufactures the highest quality wire rope in the assembling, manufacturing, and producing their control cable assemblies, which are tested multiple times to guarantee exceptional performance and durability.
Control Cable Assemblies (also known as Push-Pull Assemblies and Pull Assemblies) are used in numerous applications requiring the transmission of force. These push pull cable assemblies are flexible enough to transmit forces in multiple directions through machinery. We have built push pull control cables for the aircraft, lawn and garden, exercise equipment, medical, office equipment and automotive industries.

Some typical applications for custom push pull cables:
There are two types of Control Cable Assemblies:
Push-Pull Assemblies are used when the transmission of force is required in both directions of the assembly travel. A choke on a lawn mower engine is a good example of this.
Custom push-pull assemblies offer multidirectional control for precise and accurate control of mechanical motion. The basic design and function of push pull assemblies makes them flexible and adaptable to fit into a wide variety of applications. The solid wire fittings of push pull assemblies make it easy to attach them to an assortment of connecting points on equipment, complicated control systems, or automated machinery.
The variety of hardwired end points of push pull assemblies ensures a secure and reliable connection to any type of device. The versatility of push pull assemblies offers a dependable way of motion transmission between fixed points or ones that constantly change their relative position.
Pull Assemblies are used when the transmission of force is needed in only one direction. Think of the hood release on your car.
The unique nature of pull assemblies requires attention to the specific requirements of the application. The single direction of a pull assembly may give the impression that it is a type of device that has a simple and straight forward operation. There are other considerations that must be examined when creating a pull assembly.
Of the various factors related to pull assemblies, the most important one is the load being applied to the cable. The stroke length and stretch of the cable determine the potential pulling ability of a pull assembly. If there is too much stretch, the cable won’t be able to activate the device. In the design phase of a pull assembly, Tyler Madison’s expert engineers closely examine the pull assembly’s function to ensure proper performance.
Cover: Vinyl, HDPE or uncovered wound wire
Liner: HDPE, or unlined
Braid: wound music wire, or braided and encased in polymer coating
Conduit End Fitting Examples
When thinking about the inner wire to use in your push pull control cable, there are a number of options to consider. Even the lightest type of load requires a solid wire with core materials that are designed to fit the application. It is important to know that loads are the greatest in the pull direction, which is a major consideration when a push pull cable is being designed.
- Cable Material: galvanized steel or stainless steel
- Cable Construction: typically, these assemblies are made of 7 x 19 (most flexible), 7 x 7, or 1 x 19 (least flexible) cables
- Conduit: Most often our customers will opt for uncoated cable as it will create the least amount of friction inside the conduit, and will extend the life of the control.
- Length: there really isn’t a minimum or maximum length, just let us know your application
Ends Fittings or Terminals: we have a large selection of end fittings, including balls, ball shanks, sleeves, stamped eyes, stops, thimbles, handles/knobs, strap forks, strap eyes, and threaded studs. Others options are available as well.
Push pull controls are important components in many different industries. Automotive, aerospace, heavy equipment and more all used variations of push pull control assemblies to adjust mechanisms and activate certain parts during operation. Quality cable assemblies make all of the difference in the lifetime performance of these parts.
In the current computer age we find ourselves in, control cables have become an essential part of programming automated equipment. The reason control cables are so essential is due to their versatility and ability to be inserted into any process knowing that they will perform accurately and flawlessly.
Maybe you’re looking for more than push pull controls. If so, you’ve come to the right place!
